United States Patent O I BABY CRIB STRUCTURE John J. Kedrowski, StevensPoint, Wis.

Application September 7, 1954, Serial No. 454,515

2 Claims. (Cl. -11) This invention relates to the class of furniture,and more particularly to a novel baby crib.

The primary object of the present invention resides in the provision ofnovel structure for a crib for babies which is adapted to hold a sidemember of the crib in a vertically adjusted position.

A further object of the invention resides in the provision of a babycrib structure which has means associated with the side member of thecrib so that when the side member is raised, the bottom member islowered, and when the side member is lowered, the bottom member israised, thereby alternatively permitting access to the baby in the cribor providing maximum protection for the baby.

Still further objects of the invention reside in the provision of anovel linkage mechanism which is adapted to raise the bottom member ofthe crib when a side member is lowered, which consists of crankssupported by brackets attached to the end members of the crib andpivotally attached to connecting links which themselves are pivotallymounted on the side members. The cranks carry rollers which engage thebottom member of the bed.

Other objects and features of this invention reside in the provision ofa baby crib structure that is strong and durable, simple in constructionand operation, highly eflicient in use, and inexpensive to manufacture,thereby permitting wide distribution and utilization.

These, together with the various ancillary objects and features of theinvention which will become apparent as the following descriptionproceeds, are attained by this baby crib structure, a preferredembodiment of which has been illustrated in the accompanying drawings,by way of example only, wherein:

Figure 1 is a top plan view of the baby crib;

Figure 2 is a vertical sectional view as taken along the plane of line22 in Figure 1 illustrating the construction of the means for raisingthe bottom member when one of the side members is lowered;

Figure 3 is a vertical sectional view as taken along the plane of line3-3 in Figure 1 illustrating the construction of the spaced guides;

Figure 4 is a bottom plan view of the crib;

Figure 5 is a sectional detail view as taken along the plane of line 5-5in Figure 3, illustrating the construction of the means utilized forholding one side of the crib in a selected position; and

Figure 6 is a sectional detail view as taken along the plane of line 6-6in Figure 3.

With continuing reference to the accompanying drawings wherein likereference numerals designate similar parts throughout the various views,reference numeral 10 generally designates the baby crib comprising thepresent invention. This baby crib includes a pair of end members 12 and14 which may be of any selected configuration.

Attached to the end members 12 and 14 are vertically spaced rows ofsubstantially L-shaped brackets 16 and 18 apertured for reception ofvertically extending guides ice 20 and 22 arranged in pairs for each ofthe end members 12 and 14. The upper portions of the guides 20 and 22are serrated to form toothed portions 24 and 26, respectively.

Side members 28 and 30 are provided and these may 'be of any suitableconfiguration and may include upper and lower rails 32 and 34interconnected by spaced upright slats, as at 36, together with acentral upright 38 interconnecting the upper and lower rails 32 and 34.Fixed to each of the side members 28 and 30 are'pairs of casings 40 and42 which are attached to the upper rail 32 by means of suitablefasteners, as at 44 and 46.

The casings 40 as well as the casings 42 have slots 48 therethroughthrough which the guides 20 and 22 extend. Further, slots 50 areprovided in the sides of the casings 40 so that pivotally mounted pawls52 which are mounted on pins 54 and extend into engagement between theteeth 24 and 26 of the vertical guides 20 and 22. Actuation members 56and 58 having enlarged upper ends are attached to the pawls 52 atsuitable portions thereof. Springs 60 and 62 resiliently yieldinglyengage the enlarged head of the actuation members 56 and 58 and thecasings 40 and 42, respectively, so as to continuously urge the pawls 52into engagement with the teeth 24 and 26.

Springs 64 are provided for continuously urging the sides 30 upwardlywhen this side is lowered and the guides are resiliently mounted bymeans of springs, as at 66.

Pivotally attached to the central supporting standard 38, as at 68, area pair of connecting links 70 and 72. Attached to the end members 12 and14 are brackets 74 and 76 of substantially V-shape which have crank arms78 and 80 pivotally attached thereto, as at 82 and 84. The crank arms 78and 80 are pivotally attached, as at 86 and 88 to the connecting links,and the crank arms 78 and 80 carry in a rotatable manner rollers 90 and92 which engage the bottom 94 of the crib at the lower surface thereof.The bottom 94 may have a peripheral framework with a spring pressedforaminous central portion 96 forming a support for a mattress or thelike.

The operation of this baby crib structure is quite simple. When thisbaby crib is used for an infant, the crib may be arranged so that theside 28 is outward. Then, by depression of the actuation members 56 and58, the pawls 52 may be released, allowing the side 28 to be raised orlowered. Upon lowering of the side 28, the connecting links 52 willpivot, causing the crank arms to pivot, raising the rollers 90 and 92and thus raising the bottom member 94. It is noted that other rollers 98and 100 are connected by rods 102 and 104 to the rollers 90 and 92 andengage the bottom 94. These rollers 98 and 100 are suitably mounted onlinks as at 106 and 108 by means of connecting cranks 110 and 112 withthe links 106 and 108 serving as the brackets 74 and 76.

When the baby crib is used with an older child where there is nonecessity for raising the bottom 94, the side 30 may be raised orlowered without causing any raising or lowering movement of the bottom94. It is noted that the bottom 94 is provided with a recess or opening114 in the peripheral edge thereof so that connecting links 70 and 72can pass downwardly therethrough.

From the foregoing, the construction and operation of the device will bereadily understood and further explanation is believed to beunnecessary. However, since numerous modifications and changes willreadily occur to those skilled in the art, it is not desired to limitthe invention to the exact construction shown and described, andaccordingly, all suitable modifications and equivalents may be resortedto, falling within the scope of the appended claims.

What is claimed as new is as follows:

1. A baby crib comprising a pair of spaced opposed end members havingvertical guides attached thereto, a pairof spaced sidemembers sl-idablymounted onsaid guides between said end members, means attached to saidside members engaging said guides to hold said side members in a raisedposition, and abottom member vertically adjustable relative to saidendmembers, and means attached to said side members and said end membersfor raising said bottom member when said one of said side members islowered, said last recited means including connecting links pivotallyattached to said side members substantially centrally thereof, bracketsattached to said end members, cranks pivotally attached to saidconnecting links and said brackets, and rollers mounted onsaid cranks,said rollers engaging said bottom member.

2. A baby crib comprising a pair of spaced' opposed end membershavingvertical" guides attached thereto, a pair of spaced side membersslidably mounted on said guides between said end members, means attachedto said side members engaging said guides to hold said side,

members in a raised position, and a bottom member vertically adjustablerelative to said end members, and' means attached to said side membersand said end memof said side members is lowered, said last recited meansincluding connecting links pivotally attached to said side memberssubstantially centrally thereof, brackets attached to said end members,cranks pivotally attached to said connecting links and said brackets,and rollers mounted on said cranks, said rollers engaging said bottommember, said bottom member having openings therein, said connectinglinks extending through said openings.
